how to upgrade my dell 530 inspiron

You'll need to replace the PSU first. 300 watts isn't going to cut it with a decent card. Look for a PSU that has a single 12 volt rail like the Corsair line. Don't be fooled by watts. It's the amps on the 12 volt rail that count. As for the card, it depends on what you want to do, play games / graphics programs / blue ray etc. Your processor will limit you on high end games.
